Zhejiang Rui'an Jinda Packaging Machinery Co., Ltd. has developed a three-layer co-extruded polyolefin heat shrinkable film machine with the leading domestic level. In August 2003, it passed the appraisal of Zhejiang's new technology products.
The machine is driven by a screw. After the plastic granules are poured into the hopper, they are continuously fed into the heating machine to convert the solid plastic into a molten state. Finally, the screw quantifies the molten material, presses it at a constant temperature, and squeezes it into the rotary machine head at a constant temperature. The die gap of the gap blows in a predetermined amount of compressed air from the nose to inflate the plastic from a viscous fluid state into a highly elastic three-layer composite tubular film. The machine has advanced technology, scientific structure design, reasonable production process, high degree of automation, safe and reliable use, and can be comparable to similar foreign products in terms of technical performance, and the price is only 1/5 of that of imported products.
